Struct wasmer_cli::opts::ItemFormatOpts

pub struct ItemFormatOpts {
    pub format: Option<ItemFormat>,
}

Formatting options for a single item.

Fields

format: Option<ItemFormat>

Output format. (yaml, json, table)

This value is optional instead of using a default value to allow code to distinguish between the user not specifying a value and a generic default.

Code should usually use Self::get to use the same default format.

Implementations

impl ItemFormatOpts

pub fn get(&self) -> ItemFormat

Get the output format, defaulting to ItemFormat::Yaml.

pub fn get_with_default(&self, default: ItemFormat) -> ItemFormat

Get the output format, defaulting to the given value if not specified.
