Const `bits`

uint

Type `T`

type T = uint

Function `div_ceil`

fn div_ceil(x: uint, y: uint) -> uint

Divide two numbers, return the result, rounded up.

Arguments

x - an integer
y - an integer distinct from 0u

Return value

The smallest integer q such that x/y <= q.

Function `div_floor`

fn div_floor(x: uint, y: uint) -> uint

Divide two numbers, return the result, rounded down.

Note: This is the same function as div.

Arguments

x - an integer
y - an integer distinct from 0u

Return value

The smallest integer q such that x/y <= q. This is either x/y or x/y + 1.

Function `div_round`

fn div_round(x: uint, y: uint) -> uint

Divide two numbers, return the result, rounded to the closest integer.

Arguments

x - an integer
y - an integer distinct from 0u

Return value

The integer q closest to x/y.

Function `iterate`

fn iterate(lo: uint, hi: uint, it: &fn(uint) -> bool) -> bool

Iterate over the range [lo..hi), or stop when requested

Arguments

lo - The integer at which to start the loop (included)
hi - The integer at which to stop the loop (excluded)
it - A block to execute with each consecutive integer of the range. Return true to continue, false to stop.

Return value

true If execution proceeded correctly, false if it was interrupted, that is if it returned false at any point.

Function `next_power_of_two`

fn next_power_of_two(n: uint) -> uint

Returns the smallest power of 2 greater than or equal to n
