Enum ToolchainAvailability 

pub enum ToolchainAvailability {
    Installed,
    Missing,
    Unknown,
    Mismatch,
}

Whether a declared toolchain is usable here.

Variants

Installed

Installed, and its version answered.

Missing

The executable is not on the path.

Unknown

Nobody asked: this resolution may not run a subprocess for it, and no cache held it.

Mismatch

Installed and answering, and its version does not satisfy the one the repository declares. Reported as itself rather than as installed, because a binary that is on the path and answers the wrong version is the case a person otherwise debugs for an hour (ADR 0064). Decided only when both versions are plain dotted numbers.

Trait Implementations

impl Clone for ToolchainAvailability

fn clone(&self) -> ToolchainAvailability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ToolchainAvailability

impl Debug for ToolchainAvailability

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolchainAvailability

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for ToolchainAvailability

impl JsonSchema for ToolchainAvailability

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 ToolchainAvailability

fn cmp(&self, other: &ToolchainAvailability) -> 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 ToolchainAvailability

fn eq(&self, other: &ToolchainAvailability) -> 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 ToolchainAvailability

fn partial_cmp(&self, other: &ToolchainAvailability) -> 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 ToolchainAvailability

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
