Struct Id 

#[non_exhaustive]
pub struct Id(/* private fields */);

Opaque non-empty server-assigned identifier (RFC 8620 §1.2).

Character set: URL-safe base64 alphabet (A-Za-z0-9, -, _), max 255 octets. Clients MUST treat Id values as opaque strings — no parsing of structure.

Implementations

impl Id

pub fn into_inner(self) -> String

Consumes the value and returns the inner String.

impl Id

pub fn new_validated(s: impl Into<String>) -> Result<Self, ValidationError>

Construct an Id with RFC 8620 §1.2 syntax validation.

RFC 8620 §1.2 restricts Ids to the URL-safe base64 alphabet defined in RFC 4648 §5, excluding the pad character =. The permitted characters are therefore the ASCII alphanumerics (A-Z, a-z, 0-9), hyphen (-), and underscore (_). The string must also be non-empty and at most 255 bytes.

Errors

Returns ValidationError when the input does not satisfy RFC 8620 §1.2. The error description contains a category keyword that callers can match on if they need finer-grained handling:

• "empty" — the input was an empty string;
• "exceeds 255 bytes" — the input was longer than the spec maximum;
• "invalid character" — the input contained at least one character outside A-Z, a-z, 0-9, -, _.

Use Id::from when the value is known to be valid (e.g. a string received from a JMAP server response).

Trait Implementations
