init

Returns a map backed by memory allocated with allocator.

Handles kvs_list the same way as initComptime().

Function parameters

Parameters

kvs_list:anytype
allocator:mem.Allocator

Static string map optimized for small sets of disparate string keys.

Functions

StaticStringMap: Static string map optimized for small sets of disparate string keys.
defaultEql: Like `std.mem.eql`, but takes advantage of the fact that the lengths
eqlAsciiIgnoreCase: Like `std.ascii.eqlIgnoreCase` but takes advantage of the fact that
StaticStringMapWithEql: StaticStringMap, but accepts an equality function (`eql`).

Implementation

pub fn init(kvs_list: anytype, allocator: mem.Allocator) !Self {
    var self = Self{};
    if (kvs_list.len == 0)
        return self;

    const sorted_keys = try allocator.alloc([]const u8, kvs_list.len);
    errdefer allocator.free(sorted_keys);
    const sorted_vals = try allocator.alloc(V, kvs_list.len);
    errdefer allocator.free(sorted_vals);
    const kvs = try allocator.create(KVs);
    errdefer allocator.destroy(kvs);

    self.initSortedKVs(kvs_list, sorted_keys, sorted_vals);
    kvs.* = .{
        .keys = sorted_keys.ptr,
        .values = sorted_vals.ptr,
        .len = @intCast(kvs_list.len),
    };
    self.kvs = kvs;

    const len_indexes = try allocator.alloc(u32, self.max_len + 1);
    self.initLenIndexes(len_indexes);
    self.len_indexes = len_indexes.ptr;
    self.len_indexes_len = @intCast(len_indexes.len);
    return self;
}
