Implementations

impl ErrorCode

pub fn code(&self) -> String

Get the error code string (e.g., “P1001”).

pub fn description(&self) -> &'static str

Get a short description of the error code.

pub fn docs_url(&self) -> String

Get the documentation URL for this error.

Trait Implementations

impl Clone for ErrorCode

fn clone(&self) -> ErrorCode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ErrorCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for ErrorCode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ErrorCode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ErrorCode

fn eq(&self, other: &ErrorCode) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for ErrorCode

impl Eq for ErrorCode

impl StructuralPartialEq for ErrorCode
