Enum cargo_metadata::Message

#[non_exhaustive]
pub enum Message {
    CompilerArtifact(Artifact),
    CompilerMessage(CompilerMessage),
    BuildScriptExecuted(BuildScript),
    BuildFinished(BuildFinished),
    TextLine(String),
}

A cargo message

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CompilerArtifact(Artifact)

The compiler generated an artifact

CompilerMessage(CompilerMessage)

The compiler wants to display a message

BuildScriptExecuted(BuildScript)

A build script successfully executed.

BuildFinished(BuildFinished)

The build has finished.

This is emitted at the end of the build as the last message. Added in Rust 1.44.

TextLine(String)

A line of text which isn’t a cargo or compiler message. Line separator is not included
