Trait Rule 

pub trait Rule: Send + Sync {
    // Required methods
    fn check(
        &self,
        state: &mut RuleState,
        line: u32,
        instruction: &Instruction,
        shell: Option<&ParsedShell>,
    );
    fn code(&self) -> &RuleCode;
    fn severity(&self) -> Severity;
    fn message(&self) -> &str;

    // Provided method
    fn finalize(&self, state: RuleState) -> Vec<CheckFailure> { ... }
}

A rule that can check Dockerfile instructions.

Required Methods

fn check( &self, state: &mut RuleState, line: u32, instruction: &Instruction, shell: Option<&ParsedShell>, )

Check an instruction and potentially add failures to the state.

fn code(&self) -> &RuleCode

Get the rule code.

fn severity(&self) -> Severity

Get the default severity.

fn message(&self) -> &str

Get the rule message.

Provided Methods

fn finalize(&self, state: RuleState) -> Vec<CheckFailure>

Finalize the rule and return any additional failures. Called after all instructions have been processed.
