Struct ToolchainDecl 

pub struct ToolchainDecl {
    pub cc: Option<ToolSpec>,
    pub cxx: Option<ToolSpec>,
    pub ar: Option<ToolSpec>,
}

Manifest-shape declaration for tool selection.

Used by cabin-manifest to expose [toolchain] and [target.'cfg(...)'.toolchain] parse output as typed values. Every field is optional so omission means “no preference at this layer”.

Fields

cc: Option<ToolSpec>

cxx: Option<ToolSpec>

ar: Option<ToolSpec>

Implementations

impl ToolchainDecl

pub fn is_empty(&self) -> bool

Whether the declaration carries no fields. Used to skip emitting empty tables in serialized metadata.

pub fn get(&self, kind: ToolKind) -> Option<&ToolSpec>

Look up the preference for one tool kind.

Trait Implementations

impl Clone for ToolchainDecl

fn clone(&self) -> ToolchainDecl

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolchainDecl

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

Formats the value using the given formatter.

impl Default for ToolchainDecl

fn default() -> ToolchainDecl

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ToolchainDecl

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ToolchainDecl

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
