Struct Availability 

pub struct Availability {
    pub available: bool,
    pub reason: Option<String>,
    pub requires: Vec<Requirement>,
}

Where a command means anything, and why not when it does not.

Derived from the repository environment rather than declared per command, so that a projection reads a field instead of re-deciding. The reason is carried because the answer a person needs is never false.

Fields

available: bool

Can it be run here, now?

reason: Option<String>

Why not, in one line, when it cannot.

requires: Vec<Requirement>

What it needs, whether or not that is satisfied here.

Implementations

impl Availability

pub fn always() -> Self

Available, with nothing standing in the way.

Trait Implementations

impl Clone for Availability

fn clone(&self) -> Availability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Availability

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Availability

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Availability

impl JsonSchema for Availability

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 PartialEq for Availability

fn eq(&self, other: &Availability) -> 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 Serialize for Availability

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
