Enum actix_web::body::BodySize

pub enum BodySize {
    None,
    Sized(u64),
    Stream,
}

Body size hint.

Variants

None

Implicitly empty body.

Will omit the Content-Length header. Used for responses to certain methods (e.g., HEAD) or with particular status codes (e.g., 204 No Content). Consumers that read this as a body size hint are allowed to make optimizations that skip reading or writing the payload.

Sized(u64)

Known size body.

Will write Content-Length: N header.

Stream

Unknown size body.

Will not write Content-Length header. Can be used with chunked Transfer-Encoding.

Implementations

impl BodySize

pub const ZERO: BodySize = _

Equivalent to BodySize::Sized(0);

pub fn is_eof(&self) -> bool

Returns true if size hint indicates omitted or empty body.

Streams will return false because it cannot be known without reading the stream.

assert!(BodySize::None.is_eof());
assert!(BodySize::Sized(0).is_eof());

assert!(!BodySize::Sized(64).is_eof());
assert!(!BodySize::Stream.is_eof());

Trait Implementations

impl Clone for BodySize

fn clone(&self) -> BodySize

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for BodySize

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq<BodySize> for BodySize

fn eq(&self, other: &BodySize) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
