Implementations

impl ContentCheck

pub fn magic(prefixes: Vec<Vec<u8>>, trim_leading_whitespace: bool) -> Self

pub fn custom(f: Arc<dyn Fn(&[u8]) -> Result<(), String> + Send + Sync>) -> Self

pub fn default_binary() -> Self

pub fn check(&self, bytes: &[u8]) -> Result<(), CheckFailure>

pub fn check_prefix(&self, head: &[u8]) -> Result<(), CheckFailure>

Reject a wrong signature or HTML before downloading the remaining body. Inconclusive short prefixes pass; check_file remains authoritative.

pub fn check_file(&self, path: &Path) -> Result<(), CheckFailure>

Built-in checks stream files; only a custom predicate loads the full body.

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
