Struct salvo_core::extract::metadata::Metadata

#[non_exhaustive]
pub struct Metadata {
    pub name: &'static str,
    pub default_sources: Vec<Source>,
    pub fields: Vec<Field>,
    pub rename_all: Option<RenameRule>,
    pub serde_rename_all: Option<RenameRule>,
}

Struct’s metadata information.

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.

name: &'static str

The name of this type.

default_sources: Vec<Source>

Default sources of all fields.

fields: Vec<Field>

Fields of this type.

rename_all: Option<RenameRule>

Rename rule for all fields of this type.

serde_rename_all: Option<RenameRule>

Rename rule for all fields of this type defined by serde.
