Attribute Macro serde_with::serde_as [−][src]
#[serde_as]
Convenience macro to use the serde_as
system.
The serde_as
system is designed as a more flexible alterative to serde’s with-annotation.
Example
ⓘ
use serde_with::{serde_as, DisplayFromStr}; use std::collections::HashMap; #[serde_as] #[derive(Serialize, Deserialize)] struct Data { /// Serialize into number #[serde_as(as = "_")] a: u32, /// Serialize into String #[serde_as(as = "DisplayFromStr")] b: u32, /// Serialize into a map from String to String #[serde_as(as = "HashMap<DisplayFromStr, _>")] c: Vec<(u32, String)>, }
Alternative path to serde_with
crate
If serde_with
is not available at the default path, its path should be specified with the
crate
argument. See re-exporting serde_as
for more use case information.
