Struct TakConfigLayer 

pub struct TakConfigLayer { /* private fields */ }

tak.toml as a settings layer.

Not usage’s FileLayer: tak.toml is tak’s general config file, so most of what it holds — [bench] above all — is not a setting, and scanning the file would warn about every one of those keys. This reads the other way around: it iterates the registry’s source("config", ...) bindings and looks each dotted key up in the parsed TOML, so a key nothing declares is simply not looked at.

A missing tak.toml is fine. A syntax-broken one — or a declared key holding the wrong type — is an error rather than a warning: the file may carry [env] settings that change what gets scrubbed from a subject’s environment, and quietly applying a weaker filter than the project asked for is not a good failure.

Implementations

impl TakConfigLayer

pub fn find(start: &Path) -> Result<Self>

Find and parse tak.toml, searching upward from start.

Walking up means settings resolve the same from a subdirectory as from the repository root, exactly like Config::find.

pub fn empty() -> Self

No file at all — what a missing tak.toml resolves with, and what doctor falls back to when the file cannot be read.

Trait Implementations

impl Layer for TakConfigLayer

fn source(&self) -> SourceKind

Which kind of place this reads. Used by the scope check and reported by explain.

fn load(&self, ctx: &LayerCtx) -> Result<LayerOutput, LayerError>

Everything this layer has to say, in one pass.
