Enum ToolSource 

pub enum ToolSource {
    Cli,
    Env,
    UserConfig,
    WorkspaceConfig,
    PackageConfig,
    ExplicitConfig,
    ManifestConditional,
    Manifest,
    Default,
}

Where a tool selection ultimately came from. Recorded alongside the resolved tool so cabin metadata can show the precedence without re-deriving it.

Variants

Cli

Set by a CLI flag (--cc, --cxx, --ar).

Env

Set by an environment variable (CC, CXX, AR).

UserConfig

Set by [toolchain] in the user-level config file.

WorkspaceConfig

Set by [toolchain] in the workspace-level config file.

PackageConfig

Set by [toolchain] in the package-local config file (non-workspace single-package projects).

ExplicitConfig

Set by [toolchain] in a config file pointed at by the CABIN_CONFIG environment variable.

ManifestConditional

Set by a [target.'cfg(...)'.toolchain] table that matches the host platform.

Manifest

Set by the workspace-root [toolchain] table.

Default

Auto-detected from PATH using Cabin’s documented fallback list (c++ / clang++ / g++ for the C++ compiler, cc / clang / gcc for the C compiler, ar for the archiver).

Trait Implementations

impl Clone for ToolSource

fn clone(&self) -> ToolSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ToolSource

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ToolSource

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ToolSource

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for ToolSource

impl Eq for ToolSource

impl StructuralPartialEq for ToolSource
