getLongestPrefixIndex

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

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

    var len = @min(self.max_len, str.len);
    while (len >= self.min_len) : (len -= 1) {
        if (self.getIndex(str[0..len])) |i|
            return i;
    }
    return null;
