Enum boa_engine::string::CodePoint
source · pub enum CodePoint {
Unicode(char),
UnpairedSurrogate(u16),
}
Expand description
Represents a Unicode codepoint within a JsString
, which could be a valid
‘Unicode scalar value’, or an unpaired surrogate.

Implementations§
source§impl CodePoint
impl CodePoint
sourcepub const fn code_unit_count(self) -> usize
pub const fn code_unit_count(self) -> usize
Get the number of UTF-16 code units needed to encode this code point.
sourcepub fn encode_utf16(self, dst: &mut [u16]) -> &mut [u16]
pub fn encode_utf16(self, dst: &mut [u16]) -> &mut [u16]
Encodes this code point as UTF-16 into the provided u16 buffer, and then returns the subslice of the buffer that contains the encoded character.
§Panics
Panics if the buffer is not large enough. A buffer of length 2 is large enough to encode any code point.
