Mutable methods for crate::dnn::Dict

Required Methods§

Source

fn as_raw_mut_Dict(&mut self) -> *mut c_void

Provided Methods§

Source

unsafe fn ptr_mut(&mut self, key: &str) -> Result<DictValue>

If the @p key in the dictionary then returns pointer to its value, else returns NULL.

Source

fn set_str(&mut self, key: &str, value: &str) -> Result<String>

Sets new @p value for the @p key, or adds new key-value pair into the dictionary.

Source

fn set( &mut self, key: &str, value: &impl DictValueTraitConst, ) -> Result<DictValue>

Sets new @p value for the @p key, or adds new key-value pair into the dictionary.

Source

fn set_f64(&mut self, key: &str, value: &f64) -> Result<f64>

Sets new @p value for the @p key, or adds new key-value pair into the dictionary.

Source

fn set_i64(&mut self, key: &str, value: &i64) -> Result<i64>

Sets new @p value for the @p key, or adds new key-value pair into the dictionary.

Source

fn erase(&mut self, key: &str) -> Result<()>

Erase @p key from the dictionary.

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.
