Struct CargoTool 

pub struct CargoTool {
    pub binary_name: String,
    pub cdylib_name: Option<String>,
}

Cargo metadata and build helper for routine projects.

Discovers the first bin and optional cdylib target via cargo metadata --no-deps, then wraps cargo check, cargo build, and cdylib artifact relocation.

For installing routines into the cotis-cli cache, prefer install::install which uses workspace-aware metadata and cargo build --lib.

Fields

binary_name: String

Name of the first bin target from cargo metadata.

cdylib_name: Option<String>

Name of the first cdylib target, if any.

Implementations

impl CargoTool

pub fn new() -> Result<CargoTool, ()>

Discover Cargo targets in the current working directory’s workspace.

Runs cargo metadata --no-deps and returns the first bin target name and optional cdylib target name.

Errors

Returns Err(()) if cargo metadata fails, JSON parsing fails, or no bin target exists. Error details are not preserved; check stderr from the cargo invocation.

pub fn check(&self) -> Result<bool>

Run cargo check in the current directory.

Errors

Returns an I/O error if spawning cargo fails.

Returns Ok(false) if cargo check exits non-zero.

pub fn build( &self, out_dir: &Path, release: bool, out_file: &Path, ) -> Result<bool>

Build the project into out_dir and move the bin artifact to out_file.

Runs cargo build --target-dir <out_dir> with optional --release, then renames the built executable (appending .exe on Windows).

Errors

Returns an I/O error if spawning cargo, creating directories, or renaming fails.

Returns Ok(false) if out_dir does not exist, or if cargo build exits non-zero.

pub fn build_cdylib( &self, out_dir: &Path, release: bool, out_file: &Path, ) -> Result<bool>

Build the project’s cdylib into out_dir and move the library to out_file.

Requires Self::cdylib_name to be Some. Uses cdylib_filename for the source path under <out_dir>/<profile>/.

Errors

Returns an I/O error if spawning cargo, creating directories, or renaming fails.

Returns Ok(false) if out_dir does not exist, no cdylib target was found, or cargo build exits non-zero.

Trait Implementations

impl Debug for CargoTool

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

Formats the value using the given formatter.
