Enum CapabilityKind 

pub enum CapabilityKind {
    Query,
    Command,
    Resource,
}

What a capability is. Three kinds exist because three semantics exist: something that is executed and changes nothing, something that is executed and changes this process’s own memory, and something that is read. A command may also write the repository’s own tracked records, which its kind does not say and its execution policy does (ExecutionPolicy::writes_repository).

How long a call takes is not a kind. A read that walks every file of the layer is still a read, and the thing that makes it worth watching — that it reports as it goes and stops when it is asked to — is one property of its handler, declared with crate::capability::Executable::cancellable and carried on ExecutionPolicy.

Variants

Query

Executable and read-only: a typed handler, an input schema, an output schema.

Command

Executable and changing something: a typed handler, bound to POST over HTTP, and announced to MCP clients as not read-only. Most reach no further than this process’s own memory (a peer announcing itself); one that writes the repository’s tracked records says so on its execution policy, which is where a projection reads it.

Resource

Declarative content the repository holds: read as it is, never executed.

Implementations

impl CapabilityKind

pub fn is_executable(self) -> bool

Is a capability of this kind called, with a handler, rather than read?

use majordomus_cli::capability::CapabilityKind;
assert!(CapabilityKind::Query.is_executable() && CapabilityKind::Command.is_executable());
assert!(!CapabilityKind::Resource.is_executable());

pub fn is_read_only(self) -> bool

Does a call of this kind leave the process as it found it?

use majordomus_cli::capability::CapabilityKind;
assert!(CapabilityKind::Query.is_read_only());
assert!(!CapabilityKind::Command.is_read_only());

pub fn as_str(self) -> &'static str

The word as serialised.

Trait Implementations

impl Clone for CapabilityKind

fn clone(&self) -> CapabilityKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for CapabilityKind

impl Debug for CapabilityKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CapabilityKind

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for CapabilityKind

impl JsonSchema for CapabilityKind

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Ord for CapabilityKind

fn cmp(&self, other: &CapabilityKind) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CapabilityKind

fn eq(&self, other: &CapabilityKind) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for CapabilityKind

fn partial_cmp(&self, other: &CapabilityKind) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for CapabilityKind

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
