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.
