Enum Status

pub enum Status {
    Ok,
    BufError,
    StreamEnd,
}

Available on crate feature zlib only.

Possible status results of compressing some data or successfully decompressing a block of data.

Variants

Ok

Indicates success.

Means that more input may be needed but isn’t available and/or there’s more output to be written but the output buffer is full.

BufError

Indicates that forward progress is not possible due to input or output buffers being empty.

For compression it means the input buffer needs some more data or the output buffer needs to be freed up before trying again.

For decompression this means that more input is needed to continue or the output buffer isn’t large enough to contain the result. The function can be called again after fixing both.

StreamEnd

Indicates that all input has been consumed and all output bytes have been written. Decompression/compression should not be called again.

For decompression with zlib streams the adler-32 of the decompressed data has also been verified.

Trait Implementations

impl Clone for Status

fn clone(&self) -> Status

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Status

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

Formats the value using the given formatter.

impl PartialEq for Status

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

Tests for self and other values to be equal, and is used by ==.

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

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