Function toStringAlloc [src]

Converts self to a string in the requested base. Caller owns returned memory. Asserts that base is in the range [2, 36]. See also toString, a lower level function than this.

Prototype

pub fn toStringAlloc(self: Const, allocator: Allocator, base: u8, case: std.fmt.Case) Allocator.Error![]u8

Parameters

self: Constallocator: Allocatorbase: u8case: std.fmt.Case

Source

  pub fn toStringAlloc(self: Const, allocator: Allocator, base: u8, case: std.fmt.Case) Allocator.Error![]u8 {
    assert(base >= 2);
    assert(base <= 36);

    if (self.eqlZero()) {
        return allocator.dupe(u8, "0");
    }
    const string = try allocator.alloc(u8, self.sizeInBaseUpperBound(base));
    errdefer allocator.free(string);

    const limbs = try allocator.alloc(Limb, calcToStringLimbsBufferLen(self.limbs.len, base));
    defer allocator.free(limbs);

    return allocator.realloc(string, self.toString(string, base, case, limbs));
