Trait DecodeRecord

pub trait DecodeRecord {
    // Required method
    fn decode_record<T: HasRType>(&mut self) -> Result<Option<&T>>;

    // Provided method
    fn decode_records<T: HasRType + Clone>(self) -> Result<Vec<T>>
       where Self: Sized { ... }
}

Trait for types that decode DBN records of a particular type.

Required Methods

fn decode_record<T: HasRType>(&mut self) -> Result<Option<&T>>

Tries to decode a reference to a single record of type T. Returns Ok(None) if the input has been exhausted.

Errors

This function returns an error if the underlying reader returns an error of a kind other than io::ErrorKind::UnexpectedEof upon reading.

If the next record is of a different type than T, an Error::Conversion will be returned.

If the length property of the record is invalid, an Error::Decode will be returned.

Provided Methods

fn decode_records<T: HasRType + Clone>(self) -> Result<Vec<T>>

where Self: Sized,

Tries to decode all records into a Vec. This eagerly decodes the data.

Errors

This function returns an error if the underlying reader returns an error of a kind other than io::ErrorKind::UnexpectedEof upon reading.

If any of the records is of a different type than T, an Error::Conversion will be returned.

If the length property of any of the records is invalid, a Error::Decode will be returned.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
