Used to build StoreLimits
.
Implementations§
source§impl StoreLimitsBuilder
impl StoreLimitsBuilder
sourcepub fn new() -> Self
pub fn new() -> Self
Creates a new StoreLimitsBuilder
.
See the documentation on each builder method for the default for each value.
sourcepub fn memory_size(self, limit: usize) -> Self
pub fn memory_size(self, limit: usize) -> Self
The maximum number of bytes a linear memory can grow to.
Growing a linear memory beyond this limit will fail. This limit is
applied to each linear memory individually, so if a wasm module has
multiple linear memories then they’re all allowed to reach up to the
limit
specified.
By default, linear memory will not be limited.
sourcepub fn table_elements(self, limit: u32) -> Self
pub fn table_elements(self, limit: u32) -> Self
The maximum number of elements in a table.
Growing a table beyond this limit will fail. This limit is applied to
each table individually, so if a wasm module has multiple tables then
they’re all allowed to reach up to the limit
specified.
By default, table elements will not be limited.
sourcepub fn instances(self, limit: usize) -> Self
pub fn instances(self, limit: usize) -> Self
The maximum number of instances that can be created for a Store
.
Module instantiation will fail if this limit is exceeded.
This value defaults to 10,000.
sourcepub fn tables(self, tables: usize) -> Self
pub fn tables(self, tables: usize) -> Self
The maximum number of tables that can be created for a Store
.
Module instantiation will fail if this limit is exceeded.
This value defaults to 10,000.
sourcepub fn memories(self, memories: usize) -> Self
pub fn memories(self, memories: usize) -> Self
The maximum number of linear memories that can be created for a Store
.
Instantiation will fail with an error if this limit is exceeded.
This value defaults to 10,000.
sourcepub fn trap_on_grow_failure(self, trap: bool) -> Self
pub fn trap_on_grow_failure(self, trap: bool) -> Self
Indicates that a trap should be raised whenever a growth operation would fail.
This operation will force memory.grow
and table.grow
instructions
to raise a trap on failure instead of returning -1. This is not
necessarily spec-compliant, but it can be quite handy when debugging a
module that fails to allocate memory and might behave oddly as a result.
This value defaults to false
.
sourcepub fn build(self) -> StoreLimits
pub fn build(self) -> StoreLimits
Consumes this builder and returns the StoreLimits
.
