Struct Qmap 

pub struct Qmap { /* private fields */ }

Safe wrapper for a Qmap handle.

Implementations

impl Qmap

pub fn open( filename: Option<&str>, database: Option<&str>, ktype: u32, vtype: u32, mask: u32, flags: u32, ) -> Option<Self>

pub fn handle(&self) -> u32

pub unsafe fn from_handle(hd: u32) -> Self

Creates a Qmap handle from a raw handle ID. This should only be used for handles managed elsewhere (like in ndc C backend).

pub fn get(&self, key: *const c_void) -> *const c_void

pub fn get_str(&self, key: &str) -> Option<&str>

pub fn put(&self, key: *const c_void, value: *const c_void) -> u32

pub fn put_str(&self, key: &str, value: &str) -> u32

pub fn del(&self, key: *const c_void)

pub fn drop(&self)

pub fn iter(&self, key: *const c_void, flags: u32) -> Cursor

Trait Implementations

impl Drop for Qmap

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
