Implementations§

source§

impl SelemId

source

pub fn new(name: &str, index: u32) -> SelemId

source

pub fn empty() -> SelemId

Returns an empty (zeroed) SelemId. This id is not a usable id and need to be initialized like SelemId::new() does

source

pub fn get_name(&self) -> Result<&str>

source

pub fn get_index(&self) -> u32

source

pub fn set_name(&mut self, name: &CStr)

source

pub fn set_index(&mut self, index: u32)
