Enum futures::io::SeekFrom

pub enum SeekFrom {
    Start(u64),
    End(i64),
    Current(i64),
}

Enumeration of possible methods to seek within an I/O object.

It is used by the Seek trait.

Variants

Start(u64)

Sets the offset to the provided number of bytes.

End(i64)

Sets the offset to the size of this object plus the specified number of bytes.

It is possible to seek beyond the end of an object, but it’s an error to seek before byte 0.

Current(i64)

Sets the offset to the current position plus the specified number of bytes.

It is possible to seek beyond the end of an object, but it’s an error to seek before byte 0.

Trait Implementations

impl Clone for SeekFrom

fn clone(&self) -> SeekFrom

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SeekFrom

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

Formats the value using the given formatter.

impl PartialEq for SeekFrom

fn eq(&self, other: &SeekFrom) -> 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.
