Struct const_panic::PanicVal

pub struct PanicVal<'a> { /* fields omitted */ }

An opaque enum of the values that this crate knows how to format, along with some formatting metadata.

This has constructor functions to make a PanicVal from:

• bool
• Integers
• &str
• Arrays/Slices of primitives (with the “non_basic” feature, enabled by default)
• ShortString (with the “non_basic” feature, enabled by default)

Implementations

impl<'a> PanicVal<'a>

pub const fn from_short_str(this: ShortString, f: FmtArg) -> PanicVal<'a>

Constructs a PanicVal from a ShortString.

impl<'a> PanicVal<'a>

pub const EMPTY: Self

A PanicVal that formats to nothing.

pub const fn leftpad(&self) -> u8

How many spaces are printed before this

pub const fn rightpad(&self) -> u8

How many spaces are printed after this

impl<'a> PanicVal<'a>

pub const fn with_leftpad(self, fmtarg: FmtArg) -> Self

Sets the amount of spaces printed before this to fmtarg.indentation.

Note that only strings can be padded.

pub const fn with_rightpad(self, fmtarg: FmtArg) -> Self

Sets the amount of spaces printed after this to fmtarg.indentation.

Note that only strings can be padded.

pub const fn write_str(string: &'a str) -> Self

Constructs a PanicVal which outputs the contents of string verbatim.

Equivalent to PanicVal::from_str(string, FmtArg::DISPLAY)

pub const fn write_short_str(string: ShortString) -> Self

Constructs a PanicVal from a ShortString, which outputs the string verbatim.

pub const fn from_element_separator(
    separator: &str,
    is_last_field: IsLast,
    fmtarg: FmtArg
) -> Self

Constructs a PanicVal usable as a separator between fields or elements.

This is sensitive to the fmtarg.is_alternate flag, for more details on that you can look at the docs for Separator::to_panicval

Panics

This panics if string.len() is greater than 12.
