Struct NetrcCredentialHelper 

pub struct NetrcCredentialHelper { /* private fields */ }

Netrc-backed credential helper.

Cheap to construct: the file is read and parsed once at construction, and lookups walk the parsed list linearly (netrc files are small in practice).

Implementations

impl NetrcCredentialHelper

pub fn from_contents(content: &str) -> Self

Build from a parsed-and-already-decoded netrc body.

pub fn from_default_location() -> Option<Self>

Read the user’s default netrc file.

Tries $HOME/.netrc, falling back to $HOME/_netrc on Windows when .netrc isn’t present. Returns None when no netrc file exists, when $HOME isn’t set, or when the file is unreadable; these are not user errors, just “no creds from this source”.

pub fn from_path(path: &Path) -> Option<Self>

Read + parse path. Returns None when the file is missing or unreadable; logging a parse error is upstream’s choice but “no creds from this source” matches Helper-trait semantics.

Try to fetch credentials for query.

fn approve(&self, query: &Query, creds: &Credentials) -> Result<(), HelperError>

Tell the helper that creds worked for query.

fn reject(&self, query: &Query, creds: &Credentials) -> Result<(), HelperError>

Tell the helper that creds did not work for query.
