Std.Buffer.compare

fn

This is a callable function.

What it does

Compares len bytes between buffer a at aOff and buffer b at bOff.

Follows standard lexicographical ordering (memcmp semantics):

- Returns Some(0) if both byte sequences are identical.

- Returns Some(-1) if the slice in a is lexicographically less than b.

- Returns Some(1) if the slice in a is lexicographically greater than b.

- Returns None if either range exceeds its respective buffer bounds.

Read the signature

• The text after the name is the type checked by Pudu.
• Read arrows from left to right: inputs come first, and the final type is returned.
• & borrows a value for this call instead of moving or copying it.
• Names inside [ ] are type arguments, such as the item type held by a collection.
• Option holds Some(value) or None when no value is available.
