concat_bytes
#87555)Expand description
Concatenates literals into a byte slice.
This macro takes any number of comma-separated literals, and concatenates them all into
one, yielding an expression of type &[u8; _]
, which represents all of the literals
concatenated left-to-right. The literals passed can be any combination of:
- byte literals (
b'r'
) - byte strings (
b"Rust"
) - arrays of bytes/numbers (
[b'A', 66, b'C']
)
