u32
Expand description
32-bit unsigned integer

Implementations

fn min() -> Self

The smallest value that can be represented by this integer type.

Returns

  • [u32] - The smallest u32 value.

Examples

fn foo() {
    let val == u32::min();
    assert(val == 0u32);
}

fn max() -> Self

The largest value that can be represented by this integer type,
232 - 1.

Returns

  • [u32] - The largest u32 value.

Examples

fn foo() {
    let val == u32:max();
    assert(val == 4294967295u32);
}

fn bits() -> u64

The size of this integer type in bits.

Returns

  • [u32] - The number of bits for a u32.

Examples

fn foo() {
    let bits = u32::bits();
    assert(bits == 32);
}

fn zero() -> Self

Returns the zero value for the u32 type.

Returns

  • [u32] -> The zero value for the u32 type.

Examples

fn foo() {
    let zero_u32 = u32::zero();
    assert(zero_u32 == 0u32);
}

fn as_u64(self) -> u64

Extends a u32 to a u64.

Returns

  • [u64] - The converted u32 value.

Examples

fn foo() {
    let val = 10u32;
    let result = val.as_u64();
    assert(result == 10);
}

fn as_u256(self) -> u256

Extends a u32 to a u256.

Returns

  • [u256] - The converted u32 value.

Examples

fn foo() {
    let val = 2u32;
    let result = val.as_u256();
    assert(result == 0x0000000000000000000000000000000000000000000000000000000000000002u256);
}

Trait Implementations

fn add(self, other: Self) -> Self

fn subtract(self, other: Self) -> Self

fn multiply(self, other: Self) -> Self

fn divide(self, other: Self) -> Self

fn modulo(self, other: Self) -> Self

fn not(self) -> Self

fn eq(self, other: Self) -> bool

fn neq(self, other: Self) -> bool

Evaluates if two values of the same type are not equal.

Additional Information

This function is inherited when eq() is implemented.

Arguments

  • other: [Self] - The value of the same type.

Returns

  • [bool] - true if the two values are not equal, otherwise false.

Examples

struct MyStruct {
    val: u64,
}

impl Eq for MyStruct {
    fn eq(self, other: Self) -> bool {
         self.val == other.val
    }
}

fn foo() {
    let struct1 = MyStruct { val: 10 };
    let struct2 = MyStruct { val: 2 };
    let result = struct1 != struct2;
    assert(result);
}

fn gt(self, other: Self) -> bool

fn lt(self, other: Self) -> bool

fn binary_and(self, other: Self) -> Self

fn binary_or(self, other: Self) -> Self

fn binary_xor(self, other: Self) -> Self

fn ge(self, other: Self) -> bool

Evaluates if one value of the same type is greater or equal to than another.

Additional Information

This trait requires that the Ord and Eq traits are implemented.

Arguments

  • other: [Self] - The value of the same type.

    assert(result);
}

fn le(self, other: Self) -> bool

Evaluates if one value of the same type is less or equal to than another.

Additional Information

This trait requires that the Ord and Eq traits are implemented.

Arguments

Returns

  • [bool] - true if self is less than or equal to other, otherwise false.
