Struct system_deps::Config

pub struct Config { /* fields omitted */ }

Structure used to configure metadata before starting to probe for dependencies

Implementations

impl Config

pub fn new() -> Self

Create a new set of configuration

pub fn probe(self) -> Result<Dependencies, Error>

Probe all libraries configured in the Cargo.toml [package.metadata.system-deps] section.

The returned hash is using the toml key defining the dependency as key.

pub fn add_build_internal<F>(self, name: &str, func: F) -> Self where
    F: 'static + FnOnce(&str, &str) -> Result<Library, BuildInternalClosureError>, 

Add hook so system-deps can internally build library name if requested by user.

It will only be triggered if the environment variable SYSTEM_DEPS_$NAME_BUILD_INTERNAL is defined with either always or auto as value. In the latter case, func is called only if the requested version of the library was not found on the system.

Arguments

• name: the name of the library, as defined in Cargo.toml
• func: closure called when internally building the library. It receives as argument the library name, and the minimum version required.
