Function cuprate_epee_encoding::write_bytes

pub fn write_bytes<T: AsRef<[u8]>, B: BufMut>(t: T, w: &mut B) -> Result<()>

Write a byte array to w with write_varint.

This function:

• Writes the length of t’s bytes into w using write_varint
• Writes t’s bytes into w

It is used as the internal EpeeValue::write implementation of byte-like containers such as:

• EpeeValue::<Vec<u8>>::write
• EpeeValue::<String>::write

Errors

This will error if:

• write_varint fails
• w does not have enough capacity

Example

let t: [u8; 8] = [3, 0, 0, 0, 1, 0, 0, 0];
let mut w = vec![];

cuprate_epee_encoding::write_bytes(t, &mut w).unwrap();

assert_eq!(w.len(), 9); // length of bytes + bytes
assert_eq!(w[1..], t);
