Struct GuardRuleFile 

pub struct GuardRuleFile { /* private fields */ }

A parsed Guard rule file, ready to be evaluated against any template.

The Guard parser borrows from the source text, so the file keeps the text and re-parses it per evaluation; a syntax error is still caught once, here, at load time.

Implementations

impl GuardRuleFile

pub fn parse( name: impl Into<String>, source: impl Into<String>, ) -> Result<Self, String>

Parses source, reporting a syntax error with the file name, and records each declared rule’s name and first custom message.

pub fn name(&self) -> &str

pub fn pack(&self) -> &str

The pack the file’s rules belong to, derived from the file name.

pub fn rules(&self) -> &[GuardRuleInfo]

pub fn evaluate(&self, template: &Value) -> Result<Vec<GuardFinding>, String>

Evaluates every rule in the file against template, the authored template as CloudFormation JSON, and returns one finding per failed check. Rules that pass or are skipped by their when conditions produce nothing.
