Struct HeaderValueWrapper

pub struct HeaderValueWrapper(pub HeaderValue);

Tuple Fields

0: HeaderValue

Methods from Deref<Target = HeaderValue>

pub fn to_str(&self) -> Result<&str, ToStrError>

Yields a &str slice if the HeaderValue only contains visible ASCII chars.

This function will perform a scan of the header value, checking all the characters.

Examples

let val = HeaderValue::from_static("hello");
assert_eq!(val.to_str().unwrap(), "hello");

pub fn len(&self) -> usize

Returns the length of self.

This length is in bytes.

Examples

let val = HeaderValue::from_static("hello");
assert_eq!(val.len(), 5);

pub fn is_empty(&self) -> bool

Returns true if the HeaderValue has a length of zero bytes.

Examples

let val = HeaderValue::from_static("");
assert!(val.is_empty());

let val = HeaderValue::from_static("hello");
assert!(!val.is_empty());

pub fn as_bytes(&self) -> &[u8]

Converts a HeaderValue to a byte slice.

Examples

let val = HeaderValue::from_static("hello");
assert_eq!(val.as_bytes(), b"hello");

pub fn is_sensitive(&self) -> bool

Returns true if the value represents sensitive data.

Sensitive data could represent passwords or other data that should not be stored on disk or in memory. By marking header values as sensitive, components using this crate can be instructed to treat them with special care for security reasons. For example, caches can avoid storing sensitive values, and HPACK encoders used by HTTP/2.0 implementations can choose not to compress them.

Additionally, sensitive values will be masked by the Debug implementation of HeaderValue.

Note that sensitivity is not factored into equality or ordering.

Examples

let mut val = HeaderValue::from_static("my secret");

val.set_sensitive(true);
assert!(val.is_sensitive());

val.set_sensitive(false);
assert!(!val.is_sensitive());

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
