Struct Options 

pub struct Options {
    pub no_create: bool,
    pub io_blocks: bool,
    pub reference: Option<PathBuf>,
    pub size: Option<String>,
}

Fields

no_create: bool

Do not create any files.

io_blocks: bool

Treat size as number of IO blocks instead of bytes.

reference: Option<PathBuf>

Base size on another file.

size: Option<String>

Set or adjust the file size by size bytes.

The size argument is an integer and optional unit (example: 10K is 10*1024). Units are K,M,G,T,P,E, (powers of 1024) or KB,MB,… (powers of 1000). Binary prefixes can be used, too: KiB=K, MiB=M, and so on.

size may also be prefixed by one of the following modifying characters:

• ‘+’ extend by
• ‘-’ reduce by
• ‘<’ at most
• ‘>’ at least
• ‘/’ round down to multiple of
• ‘%’ round up to multiple of
