Struct Sentinel 

pub struct Sentinel {
    pub credential: CredentialName,
    pub form: PresentationForm,
}

A typed placeholder marking exactly where material belongs in a request whip constructs. The custodian substitutes at marked slots and nowhere else. The textual form is {{whipplescript-credential:<name>:<form>}}.

This generalizes DR-0042’s fixed whipplescript-model-broker marker: the sentinel names its handle and presentation form, so one request may carry slots for several credentials.

Fields

credential: CredentialName

form: PresentationForm

Implementations

impl Sentinel

pub fn new(credential: CredentialName, form: PresentationForm) -> Self

pub fn render(&self) -> String

The textual slot marker embedded in headers/bodies whip constructs.

pub fn parse(text: &str) -> Result<Self, String>

Parse one rendered sentinel.

pub fn find_all(text: &str) -> Result<Vec<(Range<usize>, Sentinel)>, String>

Every sentinel occurring in text, in order, with its byte range. Malformed markers (an opener with no valid close/name/form) are reported as errors rather than skipped: a slot the author believes is marked but the custodian would not substitute is a silent authentication failure at best.
