Trait CollectMeshExt

pub trait CollectMeshExt<T>: Iterator<Item = T> + Sized {
    // Required method
    fn collect_mesh<M>(self, region: Region) -> Result<M, M::Error>
       where M: BuildFromRegion<T>;
}

Mesh-aware collecting adapter.

Unlike FromIterator, this trait takes both an iterator and a Region to build a mesh:

• Meshes always require a shape (Region) supplied externally.
• Cardinality must match: the iterator must yield exactly region.num_ranks() items, or an error is returned.
• Construction goes through BuildFromRegion, which validates and builds the concrete mesh type.

In short: collect_mesh does for meshes what collect does for ordinary collections, but with shape-awareness and validation.

Required Methods

fn collect_mesh<M>(self, region: Region) -> Result<M, M::Error>

where M: BuildFromRegion<T>,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl<I, T> CollectMeshExt<T> for I

where I: Iterator<Item = T> + Sized,

Blanket impl: enables .collect_mesh(region) on any iterator of T.
