Function sonnerie::row_format::parse_row_format

pub fn parse_row_format(human: &str) -> Box<dyn RowFormat>

convert a text-based row format description to an object

the text format is one character per term, these are the characters:

• i -> 32-bit signed integer
• I -> 64-bit signed integer
• u -> 32-bit unsigned integer
• U -> 64-bit unsigned integer
• f -> 32-bit unsigned float
• F -> 64-bit unsigned float
• b[number] -> a given number of bytes: "b256" 256 bytes

Potential future types:

• decimal
• large integers, floats (128 bit, 256 bit)
• "s" -> variable size string type (maybe followed by a number to indicate "typical size"). The typical size is useful for knowing how big to make the blocks
