Struct ReadScopeSpec 

pub struct ReadScopeSpec {
    pub name: &'static str,
    pub options: &'static [OptionSpec],
}

The named scope options a reader accepts. Examples document values; they never fill a choice.

Fields

name: &'static str

The reader’s stable name, independent of an application’s source aliases.

options: &'static [OptionSpec]

Required choices, one-of groups, or optional values with a stated meaning for absence.

Implementations

impl ReadScopeSpec

pub fn check(&self, choices: &Options) -> Result<(), String>

Check caller choices using the same declarations and rules as registered pass options.

pub fn resolve(&self, choices: Options) -> Result<ReadScope, String>

Retain the caller’s exact choices. Missing required values are refused, not inferred.

pub fn record_unloaded( &self, scope: &mut ReadScope, option: &str, value: &str, source: impl Into<String>, ) -> Result<(), String>

Record a source alternative that was not loaded under this scope, without inventing payload. source is its source identity (a member, prototype or named family), not a local machine path.
