Struct Columns

pub struct Columns {
    pub column_items: Vec<Column>,
}

The Columns widget displays up to 2 columns in a card or dialog. You can add widgets to each column; the widgets appear in the order that they are specified. For an example in Google Chat apps, see Display cards and dialogs in columns.

The height of each column is determined by the taller column. For example, if the first column is taller than the second column, both columns have the height of the first column. Because each column can contain a different number of widgets, you can’t define rows or align widgets between the columns.

Columns are displayed side-by-side. You can customize the width of each column using the HorizontalSizeStyle field. If the user’s screen width is too narrow, the second column wraps below the first:

• On web, the second column wraps if the screen width is less than or equal to 480 pixels.
• On iOS devices, the second column wraps if the screen width is less than or equal to 300 pt.
• On Android devices, the second column wraps if the screen width is less than or equal to 320 dp.

To include more than 2 columns, or to use rows, use the [Grid][google.apps.card.v1.Grid] widget.

Google Workspace Add-ons and Chat apps: Columns for Google Workspace Add-ons are in Developer Preview.

Fields

column_items: Vec<Column>

An array of columns. You can include up to 2 columns in a card or dialog.

Trait Implementations

impl Clone for Columns

fn clone(&self) -> Columns

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Columns

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Columns

fn default() -> Columns

Returns the “default value” for a type.

impl Message for Columns

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for Columns

fn eq(&self, other: &Columns) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
