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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
