Struct BasicAuth 

pub struct BasicAuth { /* private fields */ }

HTTP Basic authentication (Authorization: Basic <base64(username:password)>).

Credentials are encoded per RFC 7617: base64(username ":" password).

Drop-path zeroization

The cached header string is wrapped in zeroize::Zeroizing so its buffer is overwritten with zeros before being returned to the allocator on drop. The intermediate username:password plaintext built during base64 encoding is ALSO zeroized — that buffer is the most attack-relevant artifact because it carries the raw password rather than the base64-encoded form. See BearerAuth for the threat model. (bd:JMAP-6r7c.59)

Implementations

impl BasicAuth

pub fn new(username: &str, password: &str) -> Result<Self, ClientError>

Construct a BasicAuth from a username and password.

Errors

• ClientError::InvalidArgument if username contains a colon (:), which is forbidden by RFC 7617 §2.
• ClientError::InvalidHeaderValue if the resulting header value contains characters that are not valid in an HTTP header value.
