Enum TargetSource 

pub enum TargetSource {
    Host,
    Env(String),
    Pragma(String),
    Explicit,
}

Where the TargetModel of an expansion came from.

Variants

Host

The machine the procedural macro itself was compiled for, because nothing said otherwise.

Env(String)

The CINRS_TARGET environment variable, holding this triple.

Pragma(String)

#pragma cinrs target "…", holding this triple.

Explicit

A crate::Options::target the caller set — a test, or a program driving the front end directly.

Implementations

impl TargetSource

pub fn triple(&self) -> Option<&str>

pub fn as_str(&self) -> &'static str

Where the model came from, as a diagnostic names it.

pub fn describe(&self) -> String

How the data-model assertion describes where the model came from.

Reads after “cinrs translated this unit for …”.
