Fields

rust_name: &'static str

The field name in Rust (snake_case)

output_name: &'static str

The output name for serialization — explicit rename if set, else equals rust_name

snake_case: &'static str

Pre-computed snake_case variant, e.g. "config_file"

camel_case: &'static str

Pre-computed camelCase variant, e.g. "configFile"

pascal_case: &'static str

Pre-computed PascalCase variant, e.g. "ConfigFile"

screaming_snake_case: &'static str

Pre-computed SCREAMING_SNAKE_CASE variant, e.g. "CONFIG_FILE"

kebab_case: &'static str

Pre-computed kebab-case variant, e.g. "config-file"

ty: &'static str

The Rust type as a string

is_extension: bool

Whether this field is an extension field

http_header: Option<&'static str>

HTTP header name if this field should be returned as a header

Implementations
