Struct xkbcommon::xkb::Context

pub struct Context { /* fields omitted */ }

Top level library context object.

The context contains various general library data and state, like logging level and include paths.

Objects are created in a specific context, and multiple contexts may coexist simultaneously. Objects from different contexts are completely separated and do not share any memory or state.

Implementations

impl Context

pub unsafe fn from_raw_ptr(ptr: *mut xkb_context) -> Context

contruct a context from a raw ffi pointer. This context must already been referenced as xkb_context_unref will be called at drop time

pub fn get_raw_ptr(&self) -> *mut xkb_context

get the raw pointer from this context

pub fn new(flags: ContextFlags) -> Context

Create a new context.

flags Optional flags for the context, or 0.

The user may set some environment variables to affect default values in the context.

pub fn include_path_append(&mut self, path: &Path) -> bool

append a new entry to the context’s include path returns true on success, or false if the include path could not be added or is inaccessible

pub fn include_path_append_default(&mut self) -> bool

Append the default include paths to the context’s include path.

Returns true on success.

pub fn include_path_reset_defaults(&mut self) -> bool

Reset the context’s include path to the default.

Removes all entries from the context’s include path, and inserts the default paths.

Returns true on success.yy

pub fn include_path_clear(&mut self)

Remove all entries from the context’s include path.

pub fn include_paths<'a>(&'a self) -> ContextIncludePaths<'a>

get an iterator on the include paths of this context

pub fn set_log_level(&mut self, level: LogLevel)

Set the current logging level.

The default level is xkb::LogLevel::Error. The environment variable XKB_LOG_LEVEL, if set in the time the context was created, overrides the default value. It may be specified as a level number or name.

pub fn get_log_level(&self) -> LogLevel

pub fn set_log_verbosity(&mut self, verbosity: i32)

Sets the current logging verbosity.

The library can generate a number of warnings which are not helpful to ordinary users of the library. The verbosity may be increased if more information is desired (e.g. when developing a new keymap).

The default verbosity is 0. The environment variable XKB_LOG_VERBOSITY, if set in the time the context was created, overrides the default value.

verbosity can be set from 1 to 10, higher values being more verbose. 0 would result in no verbose messages being logged.

Most verbose messages are of level xkb::LogLevel::Warning or lower.

pub fn get_log_verbosity(&self) -> i32

Trait Implementations

impl Clone for Context

fn clone(&self) -> Context

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Drop for Context

fn drop(&mut self)

Executes the destructor for this type.
