Crate zero_copy_pads 

Padding/aligning values without heap allocation.

Features:

• std (default feature):
  • Disable #![no_std].
  • Enable features that require heap allocation.

Usage:

Almost all items are documented with example codes, such as align_left, align_right, align_center_left, align_center_right, align_column_left, align_column_right, align_column_center_left, align_column_center_right, PaddedValue, PaddedColumn, Alignment, AlignLeft, AlignRight, AlignCenterLeft, AlignCenterRight, etc.

Re-exports

pub use fmt_iter;

Structs

AlignCenterLeft

Pad to both sides, place content in the middle, but shift to the left one block if it can’t be exactly central.

AlignCenterRight

Pad to both sides, place content in the middle, but shift to the right one block if it can’t be exactly central.

AlignLeft

Pad to the right, content to the left.

AlignRight

Pad to the left, content to the right.

CharCount

Treat character count as width.

ErrorOnExcess

Forbid all excesses, raise fmt::Error once encounter one.

Excess

Information about a situation where total_width is less than value.width().

ExcessHandlingFunction

Turn a function (without closure) into a ExcessHandler.

IgnoreExcess

Ignore excess, write value to formatter without padding.

Len

Treat str::len as width.

PaddedColumn

Pad all values in a collection to be of same (maximum) width.

PaddedColumnBuilder

Builder for PaddedColumn.

PaddedColumnIter

Iterator created by calling into_iter on PaddedColumn.

PaddedValue

Pad a single value.

PaddedValueBuilder

Builder for PaddedValue.

PanicOnExcess

Forbid all excesses, panic once encounter one.

UnicodeWidth

Treat UnicodeWidthStr::width as width.

UnicodeWidthCjk

Treat UnicodeWidthStr::width_cjk as width.

Enums

Alignment

Where the place the pad blocks.

PaddedColumnBuilderError

Error type for PaddedColumnBuilder

PaddedValueBuilderError

Error type for PaddedValueBuilder

Constants

UNICODE_VERSION

The version of Unicode that this version of unicode-width is based on.

Traits

ExcessHandler

What to do when the width of the value exceeds total.

Pad

Pad a value knowing the number of blocks.

UnicodeWidthChar

Methods for determining displayed width of Unicode characters.

UnicodeWidthStr

Methods for determining displayed width of Unicode strings.

Unit

All zero-sized types in this crate implement this trait.

UnitExcessHandler

All pre-defined zero-sized ExcessHandler types in this crate implement this trait.

UnitPad

All pre-defined zero-sized Pad types in this crate implement this trait.

Width

Value that has width.

Functions

align_center_left

Pad space characters both side of a value with the remainder block (if any) in the right.

align_center_right

Pad space characters both side of a value with the remainder block (if any) in the left.

align_column_center_left

Pad space characters to both sides of every value so that they all share the same width. The remainder blocks will be placed at the right.

align_column_center_right

Pad space characters to both sides of every value so that they all share the same width. The remainder blocks will be placed at the left.

align_column_left

Pad space characters to the right of every value so that they all share the same width.

align_column_right

Pad space characters to the left of every value so that they all share the same width.

align_left

Pad space characters to the right of a value.

align_right

Pad space characters to the left of a value.

error_on_excess

Create a ExcessHandlingFunction that forbids excesses.

ignore_excess

Create a ExcessHandlingFunction that ignores excesses.

panic_on_excess

Create a ExcessHandlingFunction that forbids excesses.
