Conditionally apply rule #78
Description
Let's say you have the following context:
struct ValidatorContext {
allow_non_ascii: bool
}In this case you want to apply the ascii rule conditionally on a field.
Right now you'd have to write a function like this:
fn conditional_ascii_check(value: &str, ctx: &ValidatorContext) -> garde::Result {
if ctx.allow_non_ascii {
return Ok(());
}
garde::rules::ascii::apply(&value, ())
}It would be interesting to have something like a #[garde(if)] statement.
Example:
struct ValidatorContext {
allow_non_ascii: bool
}
#[derive(Validate)]
#[garde(context(ValidatorContext as ctx))]
pub struct Data {
#[garde(if(!ctx.allow_non_ascii, ascii))]
text: String,
}
