# Function ethcore_light::cht::start_number [−] [src]

    pub fn start_number(cht_num: u64) -> u64

Get the starting block of a given CHT. CHT 0 includes block 1...SIZE, CHT 1 includes block SIZE + 1 ... 2*SIZE More generally: CHT N includes block (1 + N*SIZE)...((N+1)*SIZE). This is because the genesis hash is assumed to be known and including it would be redundant.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
