# Enum std::io::SeekFrom

1.0.0 · source ·

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

Expand description

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§

source§

### impl Clone for SeekFrom

source§

#### fn clone(&self) -> SeekFrom

Returns a copy of the value. Read more
source§

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

Performs copy-assignment from `source`. Read more
source§

### impl Debug for SeekFrom

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

Formats the value using the given formatter. Read more
source§

### impl PartialEq for SeekFrom

source§

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

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

#### 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.
