A generic trait for converting a number to a value.

Required Methods

Convert an i64 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

Convert an u64 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

Provided Methods

Convert an isize to return an optional value of this type. If the value cannot be represented by this value, the None is returned.

Convert an i8 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

Convert an i16 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

Convert an i32 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

Convert a usize to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

Convert an u8 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

Convert an u16 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

Convert an u32 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

Convert a f32 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.

Convert a f64 to return an optional value of this type. If the type cannot be represented by this value, the None is returned.
