Enum Arg 

pub enum Arg<'a> {
    Str(&'a BStr),
    String(BString),
    UInt(u64),
    SInt(i64),
    Float(f64),
    USizeRef(&'a mut usize),
}

Printf argument types. Note no implementation of ToArg constructs the owned string variant; callers can do so explicitly.

Variants

Str(&'a BStr)

String(BString)

UInt(u64)

SInt(i64)

Float(f64)

USizeRef(&'a mut usize)

Implementations

impl<'a> Arg<'a>

pub fn string(bytes: &'a BStr) -> Self

pub fn int(value: i32) -> Self

pub fn sint(value: i64) -> Self

pub fn hex(value: u32) -> Self

pub fn uint(value: u64) -> Self

pub fn float(value: f64) -> Self

pub fn pointer(value: usize) -> Self

pub fn set_count(&mut self, count: usize) -> Result<(), Error>

pub fn as_bstr(&self) -> Result<&BStr, Error>

pub fn as_uint(&self) -> Result<u64, Error>

pub fn as_sint(&self) -> Result<i64, Error>

pub fn as_wrapping_sint(&self) -> Result<u64, Error>

Unwraps Arg::UInt to u64. Unwraps Arg::SInt and casts the i64 to u64. Calling this on other variants of [Arg] is an error.

pub fn as_float(&self) -> Result<f64, Error>

pub fn as_uchar(&self) -> Result<u8, Error>
