Struct tract_hir::prelude::tract_data::internal::tract_smallvec::alloc::fmt::DebugSet 1.2.0[−][src]
A struct to help with fmt::Debug
implementations.
This is useful when you wish to output a formatted set of items as a part
of your Debug::fmt
implementation.
This can be constructed by the Formatter::debug_set
method.
Examples
use std::fmt; struct Foo(Vec<i32>); impl fmt::Debug for Foo { fn fmt(&self, fmt: &mut fmt::Formatter) -> fmt::Result { fmt.debug_set().entries(self.0.iter()).finish() } } assert_eq!( format!("{:?}", Foo(vec![10, 11])), "{10, 11}", );
Implementations
impl<'a, 'b> DebugSet<'a, 'b> where
'b: 'a,
[src]
'b: 'a,
pub fn entry(&mut self, entry: &dyn Debug) -> &mut DebugSet<'a, 'b>
[src]
Adds a new entry to the set output.
Examples
use std::fmt; struct Foo(Vec<i32>, Vec<u32>); impl fmt::Debug for Foo { fn fmt(&self, fmt: &mut fmt::Formatter<'_>) -> fmt::Result { fmt.debug_set() .entry(&self.0) // Adds the first "entry". .entry(&self.1) // Adds the second "entry". .finish() } } assert_eq!( format!("{:?}", Foo(vec![10, 11], vec![12, 13])), "{[10, 11], [12, 13]}", );
pub fn entries<D, I>(&mut self, entries: I) -> &mut DebugSet<'a, 'b> where
I: IntoIterator<Item = D>,
D: Debug,
[src]
I: IntoIterator<Item = D>,
D: Debug,
Adds the contents of an iterator of entries to the set output.
Examples
use std::fmt; struct Foo(Vec<i32>, Vec<u32>); impl fmt::Debug for Foo { fn fmt(&self, fmt: &mut fmt::Formatter<'_>) -> fmt::Result { fmt.debug_set() .entries(self.0.iter()) // Adds the first "entry". .entries(self.1.iter()) // Adds the second "entry". .finish() } } assert_eq!( format!("{:?}", Foo(vec![10, 11], vec![12, 13])), "{10, 11, 12, 13}", );
pub fn finish(&mut self) -> Result<(), Error>
[src]
Finishes output and returns any error encountered.
Examples
use std::fmt; struct Foo(Vec<i32>); impl fmt::Debug for Foo { fn fmt(&self, fmt: &mut fmt::Formatter<'_>) -> fmt::Result { fmt.debug_set() .entries(self.0.iter()) .finish() // Ends the struct formatting. } } assert_eq!( format!("{:?}", Foo(vec![10, 11])), "{10, 11}", );
