pub struct StringChars<'env> { /* fields omitted */ }

Represents an env.GetStringChars + env.GetStringLength query. Will automatically env.ReleaseStringChars when dropped.

impl<'env> StringChars<'env>

pub unsafe fn from_env_jstring(env: &'env Env, string: jstring) -> Self

Construct a StringChars from an Env + jstring.

pub fn chars(&self) -> &[jchar]

pub fn as_u16_slice(&self) -> &[u16]

Get an array of u16s. Generally UTF16, but not guaranteed to be valid UTF16.

pub fn decode(&self) -> DecodeUtf16<Cloned<Iter<u16>>>

std::char::decode_utf16(...)s these string characters.

pub fn to_string(&self) -> Result<String, DecodeUtf16Error>

Returns a new Ok(String), or an Err(DecodeUtf16Error) if if it contained any invalid UTF16.

pub fn to_string_lossy(&self) -> String

Returns a new String with any invalid UTF16 characters replaced with REPLACEMENT_CHARACTERs ('\u{FFFD}'.)
