The smallest value that can be represented by this type.

Returns

• [b256] - The smallest b256 value.

Examples

fn foo() {
    let val = b256::min();
    assert(val == b256::zero());
}

The largest value that can be represented by this type,
2256 - 1.

Returns

• [b256] - The largest b256 value.

Examples

fn foo() {
    let val == b256::max();
    assert(val == 0xFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF);
}

The size of this type in bits.

Returns

• [u64] - The number of bits for a b256.

Examples

fn foo() {
    let bits == b256::bits();
    assert(bits == 256);
}

Returns the zero value for the b256 type.

Returns

• [b256] -> The zero value for the b256 type.

Examples

fn foo() {
    let zero_b256 = b256::zero();
    assert(zero_b256 == 0x0000000000000000000000000000000000000000000000000000000000000000);
}

Converts a b256 to a u256.

Returns

• [u256] - The converted b256 value.

Examples

fn foo() {
    let val: b256 = 0x0102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f20;
    let result = val.as_u256();
    assert(result == 0x0102030405060708090a0b0c0d0e0f101112131415161718191a1b1c1d1e1f20u256);
}

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);
}

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.

Returns

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

Examples

struct MyStruct {
    val: u64,
}

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

impl Ord for MyStruct {
    fn gt(self, other: Self) -> bool {
        self.val > other.val
    }
}

impl OrdEq for MyStruct {}

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

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

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

Returns

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

Examples

struct MyStruct {
    val: u64,
}

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

impl Ord for MyStruct {
    fn lt(self, other: Self) -> bool {
        self.val < other.val
    }
}

impl OrdEq for MyStruct {}

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