LineWithName

Struct LineWithName 

Source
pub struct LineWithName<W: Write>(/* private fields */);
Expand description

An incomplete line which only has a name.

See: ContentLineWriter::start_line.

Implementations§

Source§

impl<W: Write> LineWithName<W>

Source

pub fn with_param( self, param_name: &str, param_value: &str, ) -> Result<LineWithParam<W>>

Add a parameter to the current content line.

§Errors

Returns an error if either the name or value is invalid or if an IO error occurs.

Source

pub fn with_params<'p>( self, params: impl Iterator<Item = (&'p str, &'p str)>, ) -> Result<LineWithParam<W>>

Add multiple parameters to the current content line.

§Errors

Returns an error if a name or value is invalid or if an IO error occurs.

Source

pub fn value(self, value: &str) -> Result<ContentLineWriter<W>>

Write a vale for the current content line.

Returns the original ContentLineWriter instance.

§Errors

Returns an error if the value is invalid or if an IO error occurs.

Source

pub fn without_params(self) -> LineWantValue<W>

Continue writing this line without any parameters.

This is useful for scenarios where parameters are conditional.

§Example

let line = writer.start_line("DTSTART").unwrap();

let want_value = if (condition) {
    line.with_param("TZID", "Atlantic/Reykjavik").unwrap().end_params()
} else {
    line.without_params()
};
writer = want_value.value("20250106T180000").unwrap()
