Struct EnvFiles 

pub struct EnvFiles {
    pub base: Option<PathBuf>,
    pub override_file: Option<PathBuf>,
}

Environment files selected by the application.

Missing files are ignored so production deployments can use process-level variables exclusively. The optional override replaces base and process values in an immutable configuration snapshot. The OS process environment is untouched.

Fields

base: Option<PathBuf>

Base dotenv file.

override_file: Option<PathBuf>

Local or deployment-specific override file.

Implementations

impl EnvFiles

pub fn load(&self) -> Result<EnvLoad>

Atomically installs one immutable startup configuration.

Read it through this module’s accessors and pass vars_os to child processes. Repeating the same selection returns the existing report. Selecting different files after successful initialization returns an error. A failed load leaves the resolver and the process environment unchanged.
