Expand description

Nearest / floor / ceiling conversions from floating point types

This trait is explicitly for conversions from floating-point values to integers, supporting four rounding modes.

As with Conv, the try_conv_* methods must be implemented and must fail if conversion to the expected value is not possible. If the source is non- finite (inf or NaN), then Error::Range should be returned.

The conv_* methods each have a default implementation over the try_.. variant which panics on failure. Implementations handle errors as follows:

  • In debug builds, the methods must panic
  • Otherwise, the method may panic or may return a different value; all results must be well-defined and safe.
  • Implementations provided by this library will also panic if the always_assert or assert_float feature flag is used.

The sister-trait CastFloat supports “into” style usage.

Required Methods§

Try converting to integer with truncation

Rounds towards zero (same as as).

Try converting to the nearest integer

Half-way cases are rounded away from 0.

Try converting the floor to an integer

Returns the largest integer less than or equal to x.

Try convert the ceiling to an integer

Returns the smallest integer greater than or equal to x.

Provided Methods§

Convert to integer with truncatation

Rounds towards zero (same as as).
