Struct HighSurrogate 

pub struct HighSurrogate { /* private fields */ }

A high surrogate

Implementations

impl HighSurrogate

pub const MIN: Self

Minimum possible value.

pub const MAX: Self

Maximum possible value.

pub const fn is(code_unit: u16) -> bool

Whether code_unit is a high surrogate.

Safety-usable invariant

Iff this method returns true, the safety invariant of new_unchecked() is satisfied.

pub const unsafe fn new_unchecked(code_unit: u16) -> Self

Unchecked constructor

Safety

The caller must ensure that code_unit is in the range 0xD800..=0xDBFF.

Panics

When debug assertions are enabled, panics if the safety invariant is not upheld.

pub const fn try_new(code_unit: u16) -> Result<Self, Utf16CodeUnitError>

Fallible constructor

Ok if high surrogate and Err otherwise.

pub const fn to_u16(self) -> u16

Convert to plain code unit

pub const fn to_surrogate(self) -> Surrogate

Convert to Surrogate

pub const fn try_new_with_surrogate( surrogate: Surrogate, ) -> Result<Self, Utf16CodeUnitError>

Fallible constructor given a surrogate

Ok if high surrogate and Err otherwise.
