Trait concordium_contracts_common::Seek[−][src]

pub trait Seek {
    type Err;
    fn seek(&mut self, pos: SeekFrom) -> Result<u64, Self::Err>;
}

The Seek trait provides a cursor which can be moved within a stream of bytes. This is essentially a copy of std::io::Seek, but avoiding its dependency on std::io::Error, and the associated code size increase.
