The smallest value that can be represented by this type.

pub const MAX: Self

The largest value that can be represented by this type.

pub const unsafe fn new_unchecked(value: i16) -> Self

Creates a ranged integer without checking the value.

Safety

The value must be within the range MIN..=MAX.

pub const fn get(self) -> i16

Returns the value as a primitive type.

pub const fn expand<const NEW_MIN: i16, const NEW_MAX: i16>( self, ) -> RangedI16<NEW_MIN, NEW_MAX>

pub const fn narrow<const NEW_MIN: i16, const NEW_MAX: i16>( self, ) -> Option<RangedI16<NEW_MIN, NEW_MAX>>

Attempt to narrow the range that the value may be in. Returns None if the value is outside the new range. Fails to compile if the new range is not a subset of the current range.

pub fn from_str_radix(src: &str, radix: u32) -> Result<Self, ParseIntError>

Converts a string slice in a given base to an integer.

The string is expected to be an optional + or - sign followed by digits. Leading and trailing whitespace represent an error. Digits are a subset of these characters, depending on radix:

• 0-9
• a-z
• A-Z

Panics

Panics if radix is not in the range 2..=36.
