Struct EnvFileSource 

pub struct EnvFileSource { /* private fields */ }

Loads secrets from a .env file.

The file is parsed once at construction time. Supported syntax:

• KEY=VALUE — plain value
• KEY="quoted value" — double-quoted (quotes stripped)
• KEY='quoted value' — single-quoted (quotes stripped)
• export KEY=VALUE — optional export prefix, followed by spaces or tabs (ignored)
• # comment — ignored
• Blank lines — ignored
• Inline comments: KEY=VALUE # comment (unquoted values only)

Implementations

impl EnvFileSource

pub fn load(path: impl Into<PathBuf>) -> Result<Self, SecretError>

Load from path.

Returns SecretError::FileNotFound if the file does not exist. Use this when the path was explicitly provided by the user (e.g. via --env-file).

pub fn load_optional( path: impl Into<PathBuf>, ) -> Result<Option<Self>, SecretError>

Load from path if it exists, or return None if the file is absent.

Use this for the default .env path so that projects without a .env file are not forced to create one.

pub fn len(&self) -> usize

Number of entries loaded from the file.

pub fn is_empty(&self) -> bool

Returns true if the file contained no entries.
