Struct Sheaf 

pub struct Sheaf<T: Clone> { /* private fields */ }

A sheaf on a topological space, represented by sections over open sets.

T is the type of sections (typically a ring or module).

Implementations

impl<T: Clone> Sheaf<T>

pub fn new() -> Self

Create a new empty sheaf.

pub fn add_section(&mut self, open_set: impl Into<String>, section: T)

Add a section over an open set.

pub fn section(&self, open_set: &str) -> Option<&T>

Get the section over a given open set.

pub fn add_restriction( &mut self, source: impl Into<String>, target: impl Into<String>, )

Record a restriction map (source open ⊇ target open).

pub fn num_sections(&self) -> usize

Number of open sets with sections.

Trait Implementations
