Struct std::sys_common::wtf8::CodePoint[][src]

pub struct CodePoint {
    value: u32,
}
Expand description

A Unicode code point: from U+0000 to U+10FFFF.

Compares with the char type, which represents a Unicode scalar value: a code point that is not a surrogate (U+D800 to U+DFFF).

Fields

value: u32

Implementations

Unsafely creates a new CodePoint without checking the value.

Only use when value is known to be less than or equal to 0x10FFFF.

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

Returns None if value is above 0x10FFFF.

Creates a new CodePoint from a char.

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

Returns the numeric value of the code point.

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).

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).

Append code points from an iterator to the string.

This replaces surrogate code point pairs with supplementary code points, like concatenating ill-formed UTF-16 strings effectively would.
