impl CodePoint

unsafe fn from_u32_unchecked(value: u32) -> CodePoint

Unsafely creates a new CodePoint without checking the value.

Safety

value must be less than or equal to 0x10FFFF.

fn from_u32(value: u32) -> Option<CodePoint>

Creates a new CodePoint if the value is a valid code point.

Returns None if value is above 0x10FFFF.

fn from_char(value: char) -> CodePoint

Creates a new CodePoint from a char.

Since all Unicode scalar values are code points, this always succeeds.

fn to_u32(&self) -> u32

Returns the numeric value of the code point.

fn to_lead_surrogate(&self) -> Option<u16>

Returns the numeric value of the code point if it is a leading surrogate.

fn to_trail_surrogate(&self) -> Option<u16>

Returns the numeric value of the code point if it is a trailing surrogate.

fn to_char(&self) -> Option<char>

Optionally returns a Unicode scalar value for the code point.

Returns None if the code point is a surrogate (from U+D800 to U+DFFF).

fn to_char_lossy(&self) -> char

Returns a Unicode scalar value for the code point.

Returns '\u{FFFD}' (the replacement character “�”) if the code point is a surrogate (from U+D800 to U+DFFF).
