Expand description
Trait for format marker types.
The type implementing this trait is usually not instantiated.
It’s used with a phantom type parameter of Tendril
.
Required Methods§
Provided Methods§
sourcefn validate_prefix(buf: &[u8]) -> bool
fn validate_prefix(buf: &[u8]) -> bool
Check whether the buffer is valid for this format.
You may assume the buffer is a prefix of a valid buffer.
sourcefn validate_suffix(buf: &[u8]) -> bool
fn validate_suffix(buf: &[u8]) -> bool
Check whether the buffer is valid for this format.
You may assume the buffer is a suffix of a valid buffer.
sourcefn validate_subseq(buf: &[u8]) -> bool
fn validate_subseq(buf: &[u8]) -> bool
Check whether the buffer is valid for this format.
You may assume the buffer is a contiguous subsequence of a valid buffer, but not necessarily a prefix or a suffix.
Object Safety§
This trait is not object safe.
