invalidate

Remove a key from the cache. This can force the re-creation of a texture created by ImageSource for example.

gpa is needed to store the texture for deferred destruction

Parameters

self:*Cache: *Cache
gpa:std.mem.Allocator: std.mem.Allocator
key:Key: Key

Implementation

pub fn invalidate(self: *Cache, gpa: std.mem.Allocator, key: Key) std.mem.Allocator.Error!void {
        try self.trash.ensureUnusedCapacity(gpa, 1);
        const prev = self.cache.fetchRemove(key);
        if (prev) |kv| {
            self.trash.appendAssumeCapacity(kv.value);
        }
    }
