Trait tauri::command::CommandArg
source · pub trait CommandArg<'de, R: Runtime>: Sized {
// Required method
fn from_command(command: CommandItem<'de, R>) -> Result<Self, InvokeError>;
}
Expand description
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 aCommandArg
.
- Any type that implements
Required Methods§
sourcefn from_command(command: CommandItem<'de, R>) -> Result<Self, InvokeError>
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
.
Object Safety§
This trait is not object safe.
Implementors§
impl<'de, D: Deserialize<'de>, R: Runtime> CommandArg<'de, R> for D
Automatically implement CommandArg
for any type that can be deserialized.
