[−][src]Struct nu_protocol::EvaluatedArgs
The set of positional and named arguments, after their values have been evaluated.
- Positional arguments are those who are given as values, without any associated flag. For example, in
foo arg1 arg2
, botharg1
andarg2
are positional arguments. - Named arguments are those associated with a flag. For example,
foo --given bar
the named argument would be namegiven
and the valuebar
.
Fields
positional: Option<Vec<Value>>
named: Option<IndexMap<String, Value>>

impl EvaluatedArgs
[src]
pub fn slice_from(&self, from: usize) -> Vec<Value>
[src]
Retrieve a subset of positional arguments starting at a given position
pub fn nth(&self, pos: usize) -> Option<&Value>
[src]
Get the nth positional argument, if possible
pub fn expect_nth(&self, pos: usize) -> Result<&Value, ShellError>
[src]
Get the nth positional argument, error if not possible
pub fn len(&self) -> usize
[src]
Get the number of positional arguments available
pub fn is_empty(&self) -> bool
[src]
Return if there are no positional arguments
pub fn has(&self, name: &str) -> bool
[src]
Return true if the set of named arguments contains the name provided
pub fn get(&self, name: &str) -> Option<&Value>
[src]
Gets the corresponding Value for the named argument given, if possible
pub fn positional_iter(&self) -> PositionalIter<'_>
[src]
Iterates over the positional arguments
