getIndex

Function parameters

Parameters

self:Self
str:[]const u8

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 getIndex(self: Self, str: []const u8) ?usize {
    const kvs = self.kvs.*;
    if (kvs.len == 0)
        return null;

    if (str.len < self.min_len or str.len > self.max_len)
        return null;

    var i = self.len_indexes[str.len];
    while (true) {
        const key = kvs.keys[i];
        if (key.len != str.len)
            return null;
        if (eql(key, str))
            return i;
        i += 1;
        if (i >= kvs.len)
            return null;
    }
