Trait CommandArg 

pub trait CommandArg<'de, R: Runtime>: Sized {
    // Required method
    fn from_command(command: CommandItem<'de, R>) -> Result<Self, InvokeError>;
}

Trait implemented by command arguments to derive a value from a CommandItem.

Command Arguments

A command argument is any type that represents an item parsable from a CommandItem. Most implementations will use the data stored in InvokeMessage since CommandItem is mostly a wrapper around it.

Provided Implementations

Tauri implements CommandArg automatically for a number of types.

• crate::Window
• crate::State
• T where T: serde::Deserialize
  • Any type that implements Deserialize can automatically be used as a CommandArg.

Required Methods

fn from_command(command: CommandItem<'de, R>) -> Result<Self, InvokeError>

Derives an instance of Self from the CommandItem.

If the derivation fails, the corresponding message will be rejected using InvokeMessage.

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.
