Struct jni_glue::jchar

#[repr(transparent)]
pub struct jchar(pub jchar);

Represents a Java "UTF16" code unit. This is not guaranteed to actually be a valid code unit, and should be treated much like wchar_t is treated by Rust - encoded possibly as WTF8 rather than UTF8, laden with error checking when converting to Rust character/string types, etc.

fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<jchar> for jchar

fn eq(&self, other: &jchar) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &jchar) -> bool

This method tests for !=.

fn partial_cmp(&self, other: &jchar) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &jchar) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &jchar) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &jchar) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &jchar) -> bool

impl PrimitiveArray<jchar> for CharArray

fn new<'env>(env: &'env Env, size: usize) -> Local<'env, Self>

Uses env.New{Type}Array to create a new java array containing "size" elements.

fn from<'env>(env: &'env Env, elements: &[jchar]) -> Local<'env, Self>

fn get_region(&self, start: usize, elements: &mut [jchar])

Uses env.Get{Type}ArrayRegion to read the contents of the java array from [start .. start + elements.len())

fn set_region(&self, start: usize, elements: &[jchar])

Uses env.Set{Type}ArrayRegion to set the contents of the java array from [start .. start + elements.len())

fn get_region_as_vec(&self, range: impl RangeBounds<usize>) -> Vec<T>

Uses env.GetArrayLength + env.Get{Type}ArrayRegion to read the contents of the java array from range into a new Vec.

fn as_vec(&self) -> Vec<T>

Uses env.GetArrayLength + env.Get{Type}ArrayRegion to read the contents of the entire java array into a new Vec.
