Expand description

A raw bytes buffer stored statically:

  • in wasm as a static variable
  • in debug mode on the thread local context

Required Methods§

Source

fn with_lockable_static_buffer<R, F: FnOnce(&mut LockableStaticBuffer) -> R>( &self, f: F, ) -> R

Source

fn set_external_view_target_address_handle(&self, handle: RawHandle)

Source

fn get_external_view_target_address_handle(&self) -> RawHandle

Source

fn next_handle(&self) -> RawHandle

Source

fn set_num_arguments(&self, num_arguments: i32)

Source

fn get_num_arguments(&self) -> i32

Source

fn set_flags(&self, flags: StaticVarApiFlags)

Source

fn get_flags(&self) -> StaticVarApiFlags

Source

fn is_scaling_factor_cached(&self, decimals: usize) -> bool

Source

fn set_scaling_factor_cached(&self, decimals: usize)

Provided Methods§

Source

fn flag_is_set_or_update(&self, flag: StaticVarApiFlags) -> bool

Returns true if the flag is set, false if is default (false).

If the flag is unset (false), will set it.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
