Struct ImportsBuilder 

pub struct ImportsBuilder<'a> { /* private fields */ }

Convenience builder of ImportResolver.

With help of this builder, you can easily create ImportResolver, just by adding needed resolvers by names.

Examples

use casper_wasmi::{ModuleInstance, ImportsBuilder};

let imports = ImportsBuilder::new()
    .with_resolver("env", &EnvModuleResolver)
    // Note, that ModuleInstance can be a resolver too.
    .with_resolver("other_instance", &other_instance);
let instance = ModuleInstance::new(&module, &imports)?.assert_no_start();

Implementations

impl<'a> ImportsBuilder<'a>

pub fn new() -> ImportsBuilder<'a>

Create an empty ImportsBuilder.

pub fn with_resolver<N: Into<String>>( self, name: N, resolver: &'a dyn ModuleImportResolver, ) -> Self

Register an resolver by a name.

pub fn push_resolver<N: Into<String>>( &mut self, name: N, resolver: &'a dyn ModuleImportResolver, )

Register an resolver by a name.

Mutable borrowed version.
