Trait Implementations

impl Clone for ArgPattern

fn clone(&self) -> ArgPattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArgPattern

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

Formats the value using the given formatter.

impl PartialEq for ArgPattern

fn eq(&self, other: &ArgPattern) -> 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 TryFrom<AST> for ArgPattern

fn try_from(ast: AST) -> Result<Self, Self::Error>

Like ASTPatterns, ArgPatterns are represented as ASTs, Then converted into ArgPatterns when the compiler determines it so.

type Error = String

The type returned in the event of a conversion error.
