Struct Vector

pub struct Vector;

Namespace for functions that perform encoding of vectors.

The length of a vector is restricted to at most 0x02000000, for compatibility with the Zcash consensus rules.

Implementations

impl Vector

pub fn read<R: Read, E, F>(reader: R, func: F) -> Result<Vec<E>>

where F: Fn(&mut R) -> Result<E>,

Reads a vector, assuming the encoding written by Vector::write, using the provided function to decode each element of the vector.

pub fn read_collected<R: Read, E, F, O: FromIterator<E>>( reader: R, func: F, ) -> Result<O>

where F: Fn(&mut R) -> Result<E>,

Reads a CompactSize-prefixed series of elements into a collection, assuming the encoding written by Vector::write, using the provided function to decode each element.

pub fn read_collected_mut<R: Read, E, F, O: FromIterator<E>>( reader: R, func: F, ) -> Result<O>

where F: FnMut(&mut R) -> Result<E>,

Reads a CompactSize-prefixed series of elements into a collection, assuming the encoding written by Vector::write, using the provided function to decode each element.

pub fn write<W: Write, E, F>(writer: W, vec: &[E], func: F) -> Result<()>

where F: Fn(&mut W, &E) -> Result<()>,

Writes a slice of values by writing CompactSize-encoded integer specifying the length of the slice to the stream, followed by the encoding of each element of the slice as performed by the provided function.

pub fn write_nonempty<W: Write, E, F>( writer: W, vec: &NonEmpty<E>, func: F, ) -> Result<()>

where F: Fn(&mut W, &E) -> Result<()>,

Writes a NonEmpty container of values to the stream using the same encoding as [Vector::write]

pub fn write_sized<W: Write, E, F, I: Iterator<Item = E> + ExactSizeIterator>( writer: W, items: I, func: F, ) -> Result<()>

where F: Fn(&mut W, E) -> Result<()>,

Writes an iterator of values by writing CompactSize-encoded integer specifying the length of the iterator to the stream, followed by the encoding of each element of the iterator as performed by the provided function.

pub fn serialized_size_of_u8_vec(vec: &[u8]) -> usize

Returns the serialized size of a vector of u8 as written by [Vector::write].
