Function parse_snbt_argument 

pub fn parse_snbt_argument(input: &str) -> Result<(NbtTag, usize), SnbtError>

Parses one SNBT tag and returns the byte cursor consumed by that tag.

Unlike parse_snbt, this does not consume trailing whitespace after the tag. Command parsers use the returned cursor so the command graph can own node-separating whitespace.

Errors

Returns an error when the input does not start with a valid SNBT tag.
