Struct ProjectContext 

pub struct ProjectContext {
    pub metadata: Metadata,
    pub cargo_config: Option<Table>,
    pub cargo_toml: Table,
    pub rustc_version: Option<RustcVersion>,
    pub host_triple: Option<String>,
    pub installed_linkers: InstalledLinkers,
    pub env_vars: EnvVars,
    pub os: Os,
}

All project data gathered up front. Checks are pure functions over this.

rustc_version: Option<RustcVersion>

Parsed rustc version, if it could be determined.

host_triple: Option<String>

The host target triple reported by rustc -vV, e.g. aarch64-apple-darwin. None if it could not be parsed.

installed_linkers: InstalledLinkers

Which fast linkers were found on PATH.

env_vars: EnvVars

Build-relevant environment variables.

os: Os

The operating system build-rx is running on.

Implementations

impl ProjectContext

pub fn gather(manifest_path: Option<&Path>) -> Result<Self>

Gather all project data.

manifest_path selects the project; None uses the current directory.

pub fn project_name(&self) -> &str

Get the project name from metadata.

pub fn is_workspace(&self) -> bool

Check if this is a workspace with multiple members.

pub fn declared_msrv(&self) -> Option<(u32, u32)>

The project’s declared minimum supported Rust version (rust-version), as (major, minor), read from [package] or [workspace.package].

Returns None when no MSRV is declared.
