Module traits

Source
Description

Foundational traits for arithmetic, comparison, conversion, and formatting.

Declares the lang-bound traits used throughout the stdlib (Add / Sub / Mul / Div, Eq / Ord, Not, From / Into, TryFrom / TryInto, Display / Debug, Hash, Default, Error, LowerHex, Binary) and wires primitive-type impls to host intrinsics.

Abstractions

Traits

Add

Binary addition.

Binary

Base-2 (binary) formatting.

Debug

Diagnostic formatted representation intended for developers.

Default

Produce the canonical default value for Self (0 for numerics, "" for Str, empty container, etc.).

Display

User-facing formatted representation.

Div

Binary division.

Eq

Equality comparison.

Error

Marker trait for error types.

From

Infallible construction of Self from a source value.

Hash

Produce a 64-bit hash of Self.

Into

Infallible conversion of Self into a target type.

LowerHex

Lowercase hexadecimal formatting.

Mul

Binary multiplication.

Not

Logical or bitwise negation.

Ord

Total ordering.

Sub

Binary subtraction.

TryFrom

Fallible construction of Self from a source value; returns (Result Self error).

TryInto

Fallible conversion of Self into a target type; returns (Result target error).
