Information about struct field.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

decl_name: &'static str

Field declare name in struct definition.

flatten: bool

Field flatten, this field will extracted from request.

sources: Vec<Source>

Field sources.

aliases: Vec<&'static str>

Field aliaes.

rename: Option<&'static str>

Field rename defined by #[derive(salvo(extract(rename="")))].

serde_rename: Option<&'static str>

Field rename defined by #[derive(serde(rename=""))].

metadata: Option<&'static Metadata>

Field metadata, this is used for nested extractible types.
