Struct rant::DefaultModuleResolver

pub struct DefaultModuleResolver {
    pub enable_global_modules: bool,
    pub local_modules_path: Option<String>,
}

The default filesystem-based module resolver.

Resolution strategy

This resolver uses the following strategy to locate module files:

1. If triggered by a program, the program’s containing directory is searched first.
2. The directory specified in local_modules_path is searched next. If not specified, uses the host application’s current working directory.
3. If enable_global_modules is set to true, the global modules path is searched.

Fields

enable_global_modules: bool

Enables loading modules from RANT_MODULES_PATH.

local_modules_path: Option<String>

Specifies a preferred module loading path with higher precedence than the global module path. If not specified, looks in the current working directory.

Implementations

impl DefaultModuleResolver

pub const ENV_MODULES_PATH_KEY: &'static str = "RANT_MODULES_PATH"

The name of the environment variable that used to provide the global modules path.
